Popis: Since the lightning escape from the protection system could cause severe damages to the structures and expensive equipment, lightning protection systems should be designed in such a way that the probability of direct lightning strikes can be minimized. The aim of this paper is to model and visualize the weaknesses of tall building's air termination systems against direct lightning strikes. Hence, in this paper, a numerical method is developed based on the combination of artificial bee colony algorithm, leader progression model and charge simulation method. In the proposed approach, three-dimensional modeling of lightning performance is conducted in the problem space and such features of an intelligent meta-heuristic algorithm are incorporated into the problem that let the solution space to be searched intelligently. Therefore, the lightning vulnerability of the corner points of the tall buildings is estimated and the riskiest lightning regions corresponding to each vulnerable point are determined on the simulation-starting surface on buildings. In comparison with the time-consuming conventional method, the proposed approach is also efficient in decreasing the time required to identify protection system weaknesses. A sample real structure including three tall adjacent buildings located in Kuala Lumpur is analyzed as the problem case study and the obtained results are compared with that of previous reported methods. The simulation results verify the potential of the introduced method and depict that optimization intelligent algorithms are able to achieve high-quality solutions in the face of this problem.
